Our Repair techs have comprehensive levels of experience. We constantly have the parts you need offered on every truck so we will not have to bother you a 2nd time to get your Garage Door running right. Garage Doors weigh hundreds of pounds. The complete weight of the Door is brought by the Garage Door hardware, such as the Springs, Cables, Rollers, Bearings, etc. This hardware has a beneficial life expectancy of about 5-10 years before it deteriorates and overburdens the Garage Door Opener, eventually causing it to break or stop working. The Opener is not developed to do any heavy lifting, that is the task of the Door hardware. An easy test to see if your Garage Door hardware is doing its task is this: With the Door in the completely closed position pull down on the red disconnect cable. Then try lifting the Door. If the Door is really heavy and drops of its own weight when you release the Door Springs and hardware are worn and are refraining from doing their task, putting undue pressure on the Opener.
